INVENT R gear/v, Twain, Moisoon VACUUM PUMPING UNIT This inventionrelates generally to a bilge pump; it is directed particularly to anovel gravity bilge pump comprised of a vacuum body housing severalunbalanced weights swinging around the vertical axles bilge pump andactivating water pump by a high frequency device. Two other devices areprovided to stop and to filter the water coming into the water pump.

At the present time, gravity bilge pumps have a very poor sensitivityand cannot be used inside harbors. Their mechanism is open to air anddestroyed by the dampness of the boats hull.

It is accordingly, the principal object of this invention to obviate theabove described deficiencies of a bilge pump and provide a novel gravitybilge pump having a body in form of two semi-hemispherical cases opposedby their bigger diameter, housing two unbalanced weights swinging aroundinside the said hemispherical case and contributing together to actuatea diaphragm waterpump. All these devices working in vacuum condition,the said two opposed cases being sealed by welding or by gasket.

This will provide a very sensitive pump which will be enable to keep theboats hull always dry, even when the said boats are moored.

In this connection it will be understood that the unbalanced weightshave much more power to actuate the water pump because working in vacuumcondition no air can break their swinging. Equaly the vertical position.of the master weights axle provides much more sensitivity.

Maintenance of this bilge pump has been eliminated, since the unit iscompletely sealed, and automaticaly lubricated. The mechanism is neverin contact with moisture from the hull, providing a high workingsecurity.

The advantages of. this invention will be apparent from the followingdescription when read with reference to the accompanying drawings.

- In the drawings, wherein like reference numerals denote correspondingparts throughout the several views:

FIG. I is a horizontal top view of a gravity bilge pump embodying theinvention.

FIG. 2 is an elevational cross-sectional view thereof taken along theline 2-2 of the FIG. I in the direction of the arrows.

Refering now in detail to the drawings, reference numeral in FIG. 2designates a gravity bilge pump embodying the invention and comprisesgeneraly a housing preferably constituted by two semiherriisphericalcases 16 and 17, a master unbalanced weight 18, a water pump 19 and asecond unbalanced weight 23.

Still as illustrated in FIG. 2 the gravity bilge pumps body 15 is builtin the shape to resist at the atmospheric pressure and for this purposethe top and the bottom are coniform shape and the body s wall iscylindrical. In case of building the body in steel it will be seen thatthe welded joint 20 is formed by the melting of the two strong bendededges of the two cases, in order to hold firmly the central part of thecylindrical wall and to provide durable air tight joint.

If a plastic body is used this joint 20 may be done byv gasket or glue,the outside pressure keeping the two hemispherical cases firmlytogether. The water pump support 35 is preferably of coniform shape forthe same reason.

The bilge pumps body must be set up with the boats hull in order to havethis gravity bilge pump follow the hull movements and using it, toactuate the weights.

As illustrated on FIG. 2 the vacuum work is done inside by pumping theair through the pipe 34 which will be sealed by welding when the work isdone. To obviate the pumping of lubricating oil during this vacuumoperation, the said lubricating oil will be included in a plastic bag 36fastened between the two unbalanced weights 18 and 23, the bilge pumpsbody 15 being motionless. After the said vacuum operation, the oil bag36 will be torn by moving the bilge pump 15 and the lubricant will getposition I, by gravity.

The fork 31 of the said water pump 19 carries an offset wheel 21 runningon a ring 22 this device providing a high frequency diaphragm water pumpwork. This ring 22 and the offset wheel 21 are preferably geared so theywill not slip one on the other but be firmly interdependent, so everymovement of the unbalanced weight 18 will make the diaphragms water pump19 in motion work up and down. Since the inside of housing 15 is underpartial. vacuum, atmospheric pressure on the upper side of the diaphragmin pump 19 biases the diaphragm down and therefore biases wheel 21 downon ring 22.

Of course this invention could possibly use only the unbalanced weight18, but will preferably use both of them, the small one 23 being alwaysunbalancing the big one 18 by moving its lower end when the offset ballbearing 28 is rotating with the said unbalanced weight 23 which can moveup and down and swinging around.

The unbalancing work of the weight 23 is conditioned by its weight,which must be adjusted to make it rotate faster than the rotation of themaster one 18 to provide its permanent unbalance, but the fact that thesmall weight has only the lower end of the axle 8 to move meanwhile thebig one 18 has the pump to move, makes the difference of torque betweenthe both and let the small one 23 to rotate faster than the big one 18so it will be always in front rotation of it and unbalancing it.

Any type of water pump can be used but the diaphragm type of water pumpwill be prefered, because its good work with relatively little motion ofthe said diaphragm. As, for the said ball bearing oil pump, the valvebox will be preferred but any type could be used.

Since such pumps are well known, their operation is not furtherdescribed herein.

As illustrated in FIG. 2 this water pump 19 has an inlet pipe 24 and anoutlet pipe 25, the inlet pipe 24 having a floating ball 26 used toclose the inlet circuit when the water level is too low.

As illustrated in FIG. 2 a strainer 27 keeps the pump clean.

Means are provided for automatically maintaining the proper lubricationof the said bilge pump 15. Although it is possible to use a heavy ball37 rolling reciprocatively inside a cylinder 41 and pushing the oilalternately through a hole 38 and another hole 39, it will be preferableto use another device as is hereinbelow fully described. The ball 37alternately sucks oil in openings 38 and 39 and then pushes it out asthe ball reciprocates.

As illustrated FIG. 2 this preferred device is constituted by a specialball bearing oil pump 14 having a special hub with spherical shape 33and a cylindrical bore 9 inside accurately fitting the upper end of theaxle 8, a bore 12 flowing oil through the valves box 13. Each time theaxle 8 is moving up and down because the two different motions of theunbalanced weight 23 the oil pump 14 is working, taking the lubricatingoil 1 at the bottom of the lower case 17 through the inlet pipe 11 andspraying it inside the housing 15, through the small end hole of thepipe 10. The lubricating oil will return to the housing bottom bygravity.

It will be contemplated that we may use the above described oil type ofpump as a water pump instead of using the well known diaphragms one.

As described FIG. 2 a ball bearing 4 holds the small unbalanced weight23 through a screw 2 and a spring 7 which allows it to go down, the saidball bearing 4 permitting its rotation.

It is contemplated that each time the weight 23 is moving one way or theother or both, the upper end of the said axle 8 is moving as pistoninside the bore cylinder hub 33 of the special ball bearing 14 actuatingthis oil pump 32. To secure the work of the oil pump 32 when the weight23 is swinging around it is necessary to put the screw 2 a little offcenter with respect to the central axis of housing 15. Then as weight 23swings, screw 2 will swing or rotate about the main axis causing theupper end of axle 8 to move up and down like a piston.

An oscillating ball-bearing 28 held by a screw29 in the weight 23s bodyholds the lower end of the axle 8; a liner 3 allowing the adjustment ofthe offset position of the said lower end axle 8. The weight 23 canreciprocate vertically in a rocking motion due to spring 7, and thisfurther contributes to vertical reciprocation of the axle 8.

The pump stroke is adjustable by the screw 30 to get the better work ofthe said water pump 19.

It will be understood that in this invention three ways are provided tomove the said water pump 19 The first is provided by offset wheel 21when rotated on the ring 22.

The second is provided by the offset bearing 28 when the weight 23rotates.

The third is provided by the spring 7 when the weight 23 is upwardly anddownwardly working.

It will be understood that in this invention, although the two weightsl8 and 23 could be made by plain material, they will be preferably madehollow and filled as much as needed with the adequate material to adjustthe weight of each of them, this filling being done through the twoplugs and 6.

It is contemplated that the bilge pump according this invention must beimmersed until the line 40 in FIG. 2, in order to secure the betterwork.

While I have illustrated and described herein only one form in which theinvention can conveniently be embodied in practice it is to beunderstood that this form is presented by way of example only, and notin a lirnitating sense. For example, to simplify the lubrication of themechanism we may use ever greased bearings. Also in order to improve thewater pump's work the said water pump has to be built in a way to getthe help of the vacuum force, which keeps the wheel 21 alwa s ndermechanic re ure on t e rin 22 will gush the water pump s diaphragm iiithe ray to iifi the water out-board, which work is more important thanthe suction, because the big difference of the level works pumping; thesuction level difference being at the maximum height of the bilge pumpwhile the lift out-board could be of several yards.
